he has given, at the request of H.M. Government, to matters relating 

 to the British participation in the scheme of International Investiga- 

 tions recommended by the Christiania Conference, these results are not 

 yet completed. 



Trawling experiments in the bays on the South Devon coast, similar 

 to those carried on some years ago by Mr. Stead and Mr. Holt, have 

 been resumed during the present year, our steamer Oithona being used 

 for the purpose. The investigations have been carried out by Dr. H. M. 

 Kyle, who has made monthly trawlings at fixed stations in the bays, 

 measuring and recording the most important food-fishes, and examining 

 their food and their condition as to spawning. Work of a similar 

 character has also been extended to the offshore grounds, and an 

 attempt has been made to obtain definite information as to the move- 

 ments of certain kinds of fish. Over five hundred plaice have been 

 marked in the bays and returned to the sea, and a sufficient number 

 of these have been again captured by the fishermen to demonstrate 

 an outward migration from the bays, when the spawning season is 

 coming on. 



Mr. Balfour Browne has been engaged during the year in the study 

 of the eggs and larvae of food-fishes and in experiments on the rearing 

 of larval fishes. 



Mr. Stuart Thomson has continued his work on the scales of fishes 

 as an index of age, and has already published a preliminary note upon 

 the subject in the Journal of the Association. Mr. Thomson finds that 

 in certain fishes the lines of growth are comparatively widely separated 

 from one another, in that portion of the scale formed during the warmer 

 season of the year when the rate of growth is rapid, but much less 

 widely separated in that part built up during the colder season. 



Mr. Robert Gurney has continuously occupied his Founder's table at 

 the Laboratory, and has completed a number of valuable observations 

 on the different stages in the larval development of various decapod 

 Crustacea.
